The most common reasons a 2012 INFINITI G25 tire pressure warning light stays on are a leaking tire, a wheel that no longer holds air, or a faulty tire pressure monitoring system.
  • Tire Leaking Air: A puncture, valve stem issue, or rim damage can cause a tire to leak air, leading to loss of pressure.
  • Wheel Leaking Air: A puncture or damage to the tire or rim can cause air to leak, resulting in a loss of tire pressure.
  • Tire Pressure Monitoring System: A malfunctioning tire pressure monitoring system can be caused by faulty sensors or a dead battery in the sensor units.
Proper diagnosis will determine the exact cause of your symptom, saving you money on unnecessary repairs. The diagnostic experts at RepairPal Certified shops have the right tools and experience to solve any symptom.

How much does it cost to fix a 2012 INFINITI G25 tire pressure warning light stays on?

Common Repairs

The total repair cost will vary based on the condition of your vehicle and the number of repairs needed to fix your symptom. Proper diagnosis will save you money by finding the exact repairs needed to fix your car right the first time.

When a tire pressure monitoring sensor fails, the tire pressure monitoring system control module will recognize a loss in communication and turn on the warning lamp which indicates the failure. This is most often the case. However, the tire pressure monitoring sensor may also fail by reporting incorrect tire pressures. This could cause a flat tire to go unrecognized, or a properly inflated tire to signal a low or high tire pressure warning.

When a relearn is needed, for any reason, the TPMS warning light will illuminate, and many vehicles will display a message relating to the TPMS system being inoperative or loosing communication. It is important to keep a watchful eye on tire pressures when this system is having issues because there is no warning available for underinflation or overinflation of the tires.

Wheels offer very few symptoms, but these symptoms should never be ignored. Visible cracks on the wheels may appear, especially after hitting a large bump, Most often, this will also be accompanied by loss of air from the tire on that wheel. Also, vibration in the steering wheel is very common when the tire is out of balance, and improper wheel nuts or bolts can cause creaking and popping noises to develop. Again, there are very few symptoms, but they should not be ignored.

The only symptoms requiring diagnosis for the tire pressure monitoring system warning lamp is if the warning lamp has illuminated while the tires have correct air pressure, or if the air pressure for the tires is out of specification and the warning lamp is off. This is because the overwhelming majority of cases where the TPMS lamp illuminates is due to the change in ambient temperature.

What steps should I take to diagnose the tire pressure warning light issue on my 2012 INFINITI G25?

To effectively diagnose the tire pressure warning light issue on your 2012 INFINITI G25, begin with a thorough check of the tire pressure in all four tires using a reliable tire pressure gauge. Ensure that each tire is inflated to the recommended levels outlined in your vehicle's manual, as improper inflation is a common trigger for the warning light. Next, conduct a visual inspection of the tires for any signs of damage, such as punctures, cuts, or bulges, and look for any foreign objects that may be lodged in the tread, which could lead to air leaks. If the tire pressure is correct and the tires appear undamaged, consider resetting the tire pressure monitoring system, as temporary issues can sometimes cause the warning light to activate. Refer to your owner's manual for specific instructions on how to perform this reset. If the warning light remains illuminated after these steps, it may indicate a malfunctioning sensor or a more serious underlying issue, at which point seeking assistance from a qualified mechanic or dealership is recommended for a professional diagnosis and repair. By following this diagnostic approach, you can systematically address the issue and ensure your vehicle's safety on the road.

What are the common problems that could cause the tire pressure warning light to stay on in a 2012 INFINITI G25?

When the tire pressure warning light stays on in a 2012 INFINITI G25, it is crucial to identify the underlying issues to ensure safe driving. The most frequent cause is low tire pressure, which can be easily remedied by checking and inflating the tires to the recommended levels. If the pressure is adequate, the problem may stem from a faulty tire pressure sensor that might need replacement. Additionally, the sensor's battery could be low or dead, resulting in inaccurate readings and a persistent warning light. It's also important to inspect the wiring and connections of the tire pressure monitoring system, as any faults in these areas can trigger the warning light. Lastly, the system may require recalibration to function correctly. By addressing these common problems, you can effectively resolve the warning light issue, but if it persists, consulting a professional mechanic is recommended for further diagnosis and repair.

How urgent is it to address the tire pressure warning light that stays on in a 2012 INFINITI G25?

When the tire pressure warning light remains illuminated in a 2012 INFINITI G25, it is imperative to act swiftly due to the potential safety risks and vehicle performance issues that can arise from neglecting this warning. Ignoring the light can lead to compromised handling and stability, particularly in emergency situations or challenging driving conditions, increasing the likelihood of accidents. Additionally, driving on underinflated tires can significantly reduce fuel efficiency and accelerate tire wear, leading to costly replacements. The tire pressure monitoring system serves as a critical tool for maintaining optimal tire conditions, and a persistent warning light may indicate not only low pressure but also a malfunction within the system itself. Therefore, promptly checking and adjusting tire pressure, along with investigating any underlying issues, is essential to ensure safe driving and to protect the longevity of your vehicle's tires.
